Fault Tolerant on the Grid using Distributed Data Mining ServicesAbstract – Fault tolerance is an important issue in service-oriented architectures like Grid and Cloud systems, where many and heterogeneous machines are used. Fault Tolerance is a non-functional requirement that requires a system to continue to operate, even in the presence of faults.In this work we present a flexible fault tolerant which extends the service –oriented architecture for Distributed Data Mining services on Grid for all the machines (primaries and replica), in order to have each machine both serving client requests and acting as backup for the other machines. Where as in previously a mechanism for handling machine failures in a Grid environment is proposed. By this the users can achieve failure recovery whenever a crash can occur on a Grid node involved in the computation.

Size Distribution of Atmospheric Aerosol over Semi-Arid Region: Rajkot, Gujarat Abstract –This paper presents the Size Distribution of atmospheric aerosol estimated by inversion of spectral aerosol optical depth measurement over Rajkot (22018N, 70044 E, 142 m above mean sea level) and studied for the period of two years (March 2005-07). For complete characterization of atmospheric aerosol Angstrom parameters are used. Influence of meteorological condition on aerosol optical depth is also studied. Aerosol loading inferred from Angstrom turbidity coefficient showed that it is highest in summer season. Wavelength exponent showed that this site has larger sized particles in the atmosphere in summer rather than winter and monsoon. Aerosol size distributions were predominantly bimodal type indicating the presence of both marine and land aerosols. This type of size distributions were observed over the year. The mean effective radius is highest (~ 0.52 µm)in May-June and it is lowest (~ 0.35 µm) in October, November and December. The seasonal variation of ASD showed the influence of meteorological condition as well as source region.

Impact of Physics on IndustryAbstract – On this planet nothing is unbounded and unrelated to the fundamental laws of physics. By studying physics one can understand the interconnection between different universal things. After investigating the basics of the physics, we can understand the fundamentals of other branches of science. To make magnificent growth in industrial sector, the knowledge of energy is very important. 40% of the work in manufacturing sector depends directly or indirectly on physics, this is suggested by the Institute of Physics. Millions of jobs and trillions in turnover and GDP are generated by physics in world industrial sectors. The fundamental contribution of modern physics to water, agriculture, environment, health, medical diagnostics, energy-production-store-transmission, electronic goods, space, astrophysics, cosmology, defense, information-communication technology, etc. make an unchallengeable case for how physics has enriched the nation.
